Hangzhou Lecheng Gas Equipment Co., Ltd. offers various models of Pressure Swing Adsorption (PSA) oxygen generators. With direct supply from the manufacturer, the pricing is highly competitive. The raw material for oxygen production is air, requiring no auxiliary materials, resulting in no pollution and extremely low costs.

Working Principle

?The molecular sieve oxygen generator produced by Lecheng separates air primarily through two adsorption towers filled with molecular sieves. At room temperature, compressed air undergoes filtration, dewatering, drying, and other purification processes before entering the adsorption towers. In the towers, nitrogen and other components in the air are adsorbed by the molecular sieves, enriching the oxygen in the gas phase. The oxygen flows out from the outlet and is stored in an oxygen buffer tank. Meanwhile, the molecular sieve in the other tower, having completed adsorption, is rapidly depressurized to release the adsorbed components. The two towers alternate cycles, producing low-cost oxygen with a purity of ≥90%. The automatic switching of all valves in the system is controlled by a computer.

Application Fields of PSA Oxygen Generators

??PSA oxygen generators are highly favored by users due to their significant advantages. They are widely used in metallurgical combustion support, chemical industry, environmental protection, building materials, light industry, healthcare, aquaculture, biotechnology, wastewater treatment, and other fields.

Technical Features of PSA Oxygen Generators

??Easy Installation

??Compact equipment structure, integrated skid-mounted design, small footprint, no need for infrastructure investment, and low investment cost.

??High-Quality Zeolite Molecular Sieve

??Features large adsorption capacity, high compression resistance, and long service life.

??Fail-Safe System

??Equipped with a fault alarm system and automatic startup function to ensure safe system operation.

??More Economical Than Other Oxygen Supply Methods

??PSA technology is a simple oxygen production method using air as the raw material. Energy consumption is limited to the electricity used by the air compressor, offering low operating costs, low energy consumption, and high efficiency.

??Integrated Mechanical-Electrical-Instrumentation Design for Automated Operation

??Fully automated operation controlled by imported PLC. Oxygen flow, pressure, and purity are adjustable and continuously displayed. Pressure, flow, and purity alarms can be set, with remote automatic control and detection metering, enabling truly unmanned operation. The advanced control system simplifies operation, allowing unattended operation and remote control, with real-time monitoring of various working conditions to ensure stable gas purity and flow.

??High-Quality Components Ensure Stable and Reliable Operation

??Key components such as pneumatic valves and solenoid pilot valves use imported configurations, ensuring reliable operation, fast switching speeds, a service life of over one million cycles, low failure rates, easy maintenance, and low maintenance costs.

??Continuous Oxygen Content Display and Automatic Alarm System for Exceeding Limits

??Online monitoring of oxygen purity ensures stable required oxygen purity.

??Advanced Filling Technology Ensures Equipment Lifespan

??Zeolite molecular sieves are filled using the "blizzard" method, ensuring even distribution without dead corners and reducing pulverization. The adsorption towers use multi-level airflow distribution devices and balanced automatic compression devices, keeping the zeolite molecular sieves in a compressed state to prevent fluidization during adsorption, effectively extending their service life.

??Automatic Discharge System for Non-Compliant Oxygen

??Low-purity oxygen during startup is automatically discharged, and gas is delivered only after meeting standards.

??Ideal Purity Selection Range

??Oxygen purity is easily adjustable, allowing customization between 21% and 93±2% based on user requirements.

??Unique Cyclic Switching Process

??Reduces valve wear, extends equipment lifespan, and lowers maintenance costs.

??Free Debugging and Lifetime Maintenance

??Strong technical expertise and high-quality after-sales service provide continuous technical support, ensuring worry-free operation for users.
